Komatsu's air quality reflects the Ishikawa Prefecture Sea of Japan Noto Peninsula coastal position, with consistent Sea of Japan maritime breezes providing reliable ventilation. Vehicle traffic on surrounding roads and the Komatsu Ltd. construction machinery — Komatsu being the birthplace of the global Komatsu equipment brand — and manufacturing corridor contribute local sources, while the outstanding Sea of Japan coastal exposure generally maintains Komatsu among Ishikawa's more moderately ventilated coastal industrial cities throughout most of the year.
